Regression Analysis: Unified Concepts, Practical Applications, Computer Implementation is a concise and innovative book that gives a complete presentation of applied regression analysis in approximately one-half the space of competing books. With only the modest prerequisite of a basic (non-calculus) statistics course this text is appropriate for the widest possible audience including college juniors, seniors and first-year graduate students in business and statistics, as well as professionals in business and industry. The book is able to accommodate this wide audience because of the unique, integrative approach that is taken to the teaching of regression analysis. Whereas other regression books cover regression in four chapters, beginning with a statistical review, followed by chapters on simple linear regression, matrix algebra and multiple regression, this book introduces regression and covers both simple linear regression and multiple regression in single cohesive chapter. This is made possible through an efficient, integrative discussion of the two techniques. Additionally, in the same chapter (Chapter Two) basic statistical and matrix algebra concepts are introduced as needed In order to facilitate instruction. This approach avoids the needless repetition that is often found in longer treatments of the subject, while serving to bring a collective focus to students of widely varying mathematical backgrounds.
In the antebellum South, the presence of free people of color was problematic to the white population. Not only were they possible assistants to enslaved people and potential members of the labor force; their very existence undermined popular justifications for slavery. It is no surprise that, by the end of the Civil War, nine Southern states had enacted legal provisions for the "voluntary" enslavement of free blacks. What is surprising to modern sensibilities and perplexing to scholars is that some individuals did petition to rescind their freedom. Family or Freedom investigates the incentives for free African Americans living in the antebellum South to sacrifice their liberty for a life in bondage. Author Emily West looks at the many factors influencing these dire decisions -- from desperate poverty to the threat of expulsion -- and demonstrates that the desire for family unity was the most important consideration for African Americans who submitted to voluntary enslavement. The first study of its kind to examine the phenomenon throughout the South, this meticulously researched volume offers the most thorough exploration of this complex issue to date.
Organized" and "innovation" are words rarely heard together. But an organized approach to innovation is precisely what America needs today. This book presents a blueprint for coordinating technology breakthroughs to advance America's global competitiveness and prosperity. That prosperity is at risk. As other nations bolster technology innovation efforts, America's research, development, and commercialization enterprise is falling behind. An "innovation gap" has emerged in recent decades, where US universities focus on basic research and industry concentrates on incremental product development. The country has failed to address the innovation gap because of three myths--innovation is about lone geniuses, the free market, and serendipity. These myths blind us from recognizing our dysfunctional system of unorganized innovation. In Organized Innovation, Currall, Frauenheim, Perry and Hunter provide a framework for optimizing the way America creates, develops, and commercializes technology breakthroughs. A roadmap for universities, business, and government, the book is grounded in the authors' seminal study of the National Science Foundation's Engineering Research Center program, which has returned to the US economy more than ten times the funding invested in it. For too long, our approach to technology innovation has been unorganized. The authors enable us to turn the page. They show us how to organize innovation for a more prosperous, hopeful future.
